摘要:
推导了斜交网格筒结构子模块的侧向刚度、剪切转角和弯曲转角的简化计算式.通过结构腹板角部斜柱的轴向应变与子模块变形转角之间的关系,建立了子模块变形转角的计算方法,并通过SAP2000软件进行了验证.提出了通过斜交网格筒结构各子模块的变形转角,来控制其在弹性阶段时的侧向刚度及变形能力.结果得出:剪切刚度和弯曲刚度均随着斜柱角度的增大而减小;在相同的侧向荷载作用下,随着斜柱角度的增大,剪切转角与弯曲转角的比值逐渐增大;变形转角受斜柱角度变化的影响比较明显,建议根据结构具体的几何参数,不同斜柱角度的结构应采取不同的弹性位移角限值.
Abstract:
The simplified calculation formula of the shear angle and the bending angle of the sub module of the diagrid tube is derived. By the relationship between the axial strain of the inclined column of the structure and the harmful angle of the sub module, the calculating formula of the harmful angle is established. And it was verified by SAP2000. The lateral stiffness and deformation capacity of the structure in the elastic stage are proposed by using the threshold value of the sub module of the bottom sub module. The results show that both the shear stiffness and the bending stiffness decrease with the increase of the angle of the inclined column; With the increase of the angle of the inclined column, the ratio of the shear angle and the bending angle increases gradually; The influence of the angle of the inclined column on the side of the structure under the lateral load is obvious. According to the geometrical parameters of the structure, the structure of the different angle of inclined column should be taken to different elastic displacement angle limit.
